' AUGUSTUS W. DRAKE, on LATTIMER MINES, PENNSYLVANIA.

To all whom it may concern.-

Be it known that I, AUGUSTUS W. DRAKE, a citizen of the United States,'residing at Lattimer Mines, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Compressed-Air ater-Elevator, of which the following is aspecification.

This invention relates to improvements in that class of mechanism employed for elevating liquids in which the force of fluid under pressure is employed as the elevating .medium.

. The principal object in view is the provision of exceedingly-simple mechanism of a novel nature which is compact, so that it may be readily introduced into a well of small bore, does not depend for its operation upon an airtight well-casing, is economical in the use of air, and, furthermore, is made up of parts or elements that are not liable to leak or become deranged in practical operation. I

The invention resides in a distributing aircharnloer surrounding the upperportion of the delivery-pipe, a plurality of supplypipes leading from said chamber and having com-' munication with the delivery-pipe at different depths, and valves for controlling the supply of air to any one of said pipes from the said chamber, whereby only one inlet-pipe is necessary, requiring the use of but a single strainer.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in elevation of the structure. Fig.9 is a vertical longitudinal sec tional view through aportion of the same. Fig.3 is a cross-sectional view on the line 3 3 of Fig. 1. Fig. 4 is a horizontal sectional view through the chamber or casing-ring, and

Fig. 5 is a detail sectional view on the line 5 5 V of Fig. 2.

Similar reference-numerals designate corresponding parts in all theiigures of the drawings. V

In theembodirnent illustrateda deliverypipe 6 is employed. which may, as usual, he of sections and of any diameter desired. About the upper portion of this delivery-pipe is arranged a casing 7, constituting a guide and support for the same, said delivery-pipe depending below this casing into the well and extending above the same, Where it may be provided with an elbow coupling or nozzle 8. Surrounding the upper end of the pipe above Specification of Letters Patent. Application filed March 11, 1905. Serial No. 249,637.

COMPRESSED-AIR WATER-ELEVATOR. 1

Patented Sept. 26, 1905.

and in spaced relation to the casing is a circul'ar tubular casing-ring 9, that snugly receives the delivery-pipe, as shown in Figs. 2. and 3, but is separate therefrom. This casing'constitutes a chamber for fluid under pressure' and is provided on its under side with a plurality of depending: nipples 10, having threaded bores. In thepresent embodiment five have been shown, though more or less may be employed, as desired.

A plurality of supply-pipes 11 are provided, three being shown in the present instance, which pipes have their upperends threaded into certain of the nipples'lO, said pipes ex tending downwardly through the casing 7 on opposite sides of the delivery-pipe. Their lower ends are connected to offset nipples 12, formed on couplings 13, located in the delivery-pipe 6 at diiferent depths, or, in other WOIdS; at different distances from the chamher 9. The nipples 12 have channels 14, which communicate with the interior of the delivery-pipe 6. The passage of fluid under pressure through-these various supply-pipes 11 is controlled by suitable valves 15, located in the pipes and arranged between the chamber 9 and the-top of the casing. The nipples 10 not in use maybe closed by suitable plugs 16. Fluid under pressure is supplied to the until this level is exhausted of water, after.

which the valve controlling the shortest pipe is closed, thereby preventing the blowing 01f or-escape ofair.

inlike manner, so that as the level is lowered the pump may still be operated. In case the well is deepened after the apparatus has been installed it will be apparent that by remov- 5 ing one or more of the plugs 16 other supplypipes may be coupled to the chamber.

The structure, it will be noted, is eXceed ingly simple. There is no necessity for a packed well-casing to prevent the leakage be- The second and third pipes I00 are then consecutively opened and controlled tween the same and the surrounding earth. Thedelivery-pipe with the supply-pipes alongside the same can be readily introduced into a well, and the parts are such that there is little liability of derangement or leakage.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing anyof the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a pump of the class described, the combination with a chamber for fluid under pressure, of a delivery-pipe passing directly and centrally through the chamber, said chamber thus surrounding the upper portion of the pipe, a plurality of supply-pipes leading from said chamber and having communication with the delivery-pipe at different distances from the chamber, and means for supplying fluid under pressure to thechamber.

2. In a pump of the class described, the combination with a delivery-pipe, of an annular chamber for fluid under pressure surrounding the upper portion of the pipe, a plurality of downwardly-extending supply-pipes leading from said chamber and of less cross-sectional area than the same, said supply-pipes being located on opposite sides of the deliverypipe exteriorly thereof and having communication with the same at different depths,valves controlling the supply of fluid from the chamber through the pipes, and a valved supplypipe connected to the chamber.

3. In a pump of the class described, the combination with an upright delivery-pun, of a circular single-piece tubular easing-ring snugly surrounding the upper end ol the delivery-pipe and separate therefrom, said ring having a plurality of integral nipples depending from its under side, a plurality of supply pipes threaded into said nipples and extending downwardly alongside the deli\'er \'-pipe and on opposite sides of the same, said supply-pipes having communication attheir lower ends with the delivery-pipe atdifl'erentdepths, valves for controlling the passage of fluid through said pipes, and means for supplying fluid under pressure to the easing-ring.

4:. In a pump of the class described, the combination with a tubular casing, of an upright delivery-pipe extending longitiulinally through and above and below the same, a tubular casing-ring surrounding the deliverypipe above the casing and constituting a chamber for fluid under pressure, a plurality ol downwardly-extending su1. ply-pipes connected to the chamber, extending downwardly through the casing exteriorly of the deliverypipe and communicating with said deliverypipe at different depths, controlling-valres in the pipes between the chamber and the top of the casing, and a valved supply-pipe connected to the casing-ring.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

AUGUSTUS DRAKE.
